Question

The round wading pool at the Greenville Community Center has a diameter of 8 feet. What is the pool's circumference? use 3.14 for pi

Answer 1

The circumference of pool is 25.12 feet

Solution:

Given that round wading pool at the Greenville Community Center has a diameter of 8 feet

Therefore,

Diameter = 8 feet

We know that,

$Radius = \frac{diameter}{2}\\\\Radius = \frac{8}{2}\\\\Radius = 4$

Thus radius is 4 feet

The circumference of circle is given by formula:

$C = 2 \pi r$

Where, "r" is the radius of circle

Substitute r = 4

$C = 2 \times 3.14 \times 4\\\\C = 25.12$

Thus circumference of pool is 25.12 feet
